August 12, 1929. Serial No. 385,272.

This invention relates to machines for apilying pressure to the bottoms of shoes, for example to shape the soles to the contours of the lasts, and in some of its aspects has more particular reference to machines of that type in which the pressure is applied at one time to all the portions of the shoe bottom that are treated by the pressing means, as distinguished from machines-in which the pressure is applied successively to different portions, as by means of a roll. The invention is herein illustrated as applied to the shaping of the shank portion of the shoe bottom, for which it has special advantages, but it is to be understood that in various aspects it is not thus limited in its applicability.

In the manufacture of some kinds of shoes it i advantageous to shape the shank portion of the solo by diiferent treatment from "a lthat applied at the forepart, for example by the use of pressing means that operates on substantially all portions of the shank simultaneously, as distinguished from a roll preferably used at the forepart, as explained in lLetters Patent No. 1,'Z90,19l, granted on January 27, 1931 upon an application of E. E. l Vinkley. Such treatment is especially desirable in operating upon womens shoes of certain kinds or styles in which the shank Iportion of the shoe bottom has pronounced lateral and lengthwise curvatures and in which the shank portion of the sole is pro-- vided with tin edges that should lie close to the upper in the finished shoe. In order to Iimpart the required shape to the shank portion of the sole of such a shoe it is necessary to use means that will apply heavy pressure throughout the length and breadth of the shank notwithstanding the comparatively Isharp curvatures that are p esent on this por not approximating very closely the shape of any particular style or size of shoe, the yieldability of thepad being depended upon toconform it properly to: theshoe in each instance. More particularly, in the construction shown the pad has a pressing face co'nvexlycurved lengthwise of the shoe about I an axis of revolution and substantially straight widthwise of the shoe, the radius of curvature of the pressing face decreasing progressively in length in a direction width- Wise of the shoe so that the face has a substantially conical contour. Itwill be understood that the portion of the pad which has the more extended curvature is arranged to operate at that side of the shoe bottom which is adjacent to the inner side of the shoe, where the shank portion of the shoe bottom has more of an upward slope and a more extended curvature'lengthwise of the shoe than at the outer side of the shoe. Preferably also, as illustrated, the arrangement is such that the pressing face of the pad is inclined somewhat relatively to the direction of the height of the shoe and the axis of its curvature extends in approximately parallel relation to the ball line of the shoe. In view of the substantially straight contour of the pressing. face widthwise of the shoe, the pad accentuates. its pressure first on the intermediate portion of the sole and then as it yields brings heavy pressure to bear also in locations at and near the opposite side edges of the sole. The pad thus wraps itself progressively around the laterally convex curvature of the shoe bottom without any danger that the amount of pressure applied to the sole will be unduly, limited by premature engagement of the'pad with the upper of the shoe above the sole. To render the pad sufficiently yielding to conform properly to the shoe withoutthe necessity for the use of rubber that is too soft to apply as much pressure as is desirable for the best results, the pad herein shown has a thickness heightwise of the shoe equal to its extent lengthwise of the shoe, the illustrated pad having the shape of a frusto-conical roll the diameter of the shoe-pressing portion of which is somewhat greater than the length of the shank of the shoe. It will be evident that the requirement as to yieldability does not necessitate the use of a pad of this particular shape, but the construction illustrated'has the advantage, among others, that the pad may be turned to present different portions in operating position in case any part should become deformed through long continued use. i

Preferably, as illustrated, there is provided over the pressing face of the yieldable pad a cover of less yi'eldable material for engagement with the shoe, since it is found that better results'are secured by the use, for example, of a leather cover in engagement with the shoe than by direct contact of the pad with the shoe; and further novel features of the invention are to be recognized in the combination and arrangement thus provided. As disclosed, the arrangement is such that there is provlsion for relative creeping movement between the cover and the pad in the pressing operation, which facilitates relative yield of different portions of the rubber pad in such manner as to conform readily to the shape of the shoe and to apply the required pressures on different portions '2 of the shoe bottom. For the purpose in View, the cover, as shown, is not secured in any way .to the pad, but to the pad holder, andv it is fastened to the latter only at those extremities of the. cover which are opposite in thedirection of the length of the shoe, its

. of the illustrated construction that the pad may be substantially reversed end for end to position it for operation on both right and left shoes.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by refcrence to the accompanying drawings and thereafter pointed out in the claims.

7 In the drawings,

Fig. 2 is a vertlcal section through a pervVvinkley on January tion of the machine, showing a shoe under pressure as in Fig. 1, the shoe-pressing means being sectioned in a plane substantially mid- 2, but illustrating the positions of the parts a at the beginning of the pressure-applying operation; and

Fig. 4 is a section on substantially the same plane as that of Fig. 3, but showing the parts as positioned at the end of the pressure-applying operation, as in Figs. 1 and 2. I The invention is illustrated as applied to a machine of the same type as that disclosed in Letters Patent No. 1,549,243, granted on August 11, 1925 uponan application of E. E. WVinkley, with portions of the machine constructed in accordance with the further disclosure of Letters Patent No. "1,790,192, granted upon another application of E. E. 27, 1931 although it is to be understood that the invention is not limited to machines of that particular type. Machines of that type are twin machines, comprising two sets of mechanisms whereby one shoe is subjected to pressure simultaneously with the release from pressure of another shoe previously operated upon. Only one of the two sets of mechanisms is herein illustrated or need be referred to for an understanding, of the present invention. As shown in Fig. 1, and as more fully illustrated in the above-men'- tioned Letters Patent "No. 1,549,243, the machine is provided with a pair of vertical rods 10 on which there is adjustably secured a casting 12 which serves as a support for downwardly extending arms 14 and 16 of a jack which positions the shoe and supports it against the upwardly directed pressure of the pressing means. The arm 14 is provided with a pin 18 for engaging the heel end of the last in its spindle hole and the arm 16 is provided with means including a rubber pad 20 for supporting the last and the shoe along the instep and in the hollow back ofthe toe, as more fully disclosed in the above-mentioned Letters Patent No. 1,790,- 192.

Mlounted for vertical sliding movement on the rods 10 is a carrier 22 on which is mounted the means more particularly hereinafter described for applying pressure'to the bottom of the shank portion of the shoe. For imparting upward and downward movements to the carrier 22 there is provided a link 24 and other mechanism not herein shown in detail, since it is fully disclosed in the above-mentioned Letters Patent No. 1,549,243. It will be understood that the shoe is mounted on the jack by the operator when the carrier 22 is in its lowermost position, and that in the operation of the machine the carrier and the shoe-pressing means side of the shoe bottom.

supported thereon are moved upwardly to apply the pressure to the shoe, after which the machine comes automatically to a stop. In the next operation of the machine the shoe is released by downward movement of the carrier 22 simultaneously with the application of pressure to another shoe by the other set of mechanism.

The invention 1s illustrated by reference to the shaping of the shank portion of the portion of the last, illustrated, has pronounced lengthwise and lateral curvatures, and tie outsole at tie shank has comparatively thin edges which should lie close to the upper in the finished shoe. For shaping the shank portion of the outsole to the contour of the last and for pressing its edges close to the upper, the machine herein shown provided with a pressing pad 26 of yield able material, comprising preferably a block of rubber, which has the form of the frustum of a cone or of a conical roll arranged with its axis a 3) extending widthwise of the shoe and so positioned that its larger end operates in a location adjacent to the inner side of the shoe, the shoe illustrated being a left shoe. The pad 26 thus presents toward the shank portion of the bottom of the shoe a pressing face which is substantially straight widthwise of the shoe and is convexly curved lengthwise of the shoe on a radius which decreases progressively in length from the inner side of the shoe bottom to the outer side. side of the shank portion of the shoe bottom there is more of an upward slope than at the outer side and also a more extended concave curvature lengthwise of the shoe, and it is in view of this condition that the conical pad is arranged with its larger end at the inner It is considered preferable to position the pad so that its pressing face is inclined laterally of the shoe relatively to the direction of the height of the shoe, as illustrated in Fig. 4 where the f; axis a of the conical pad is represented as substantially perpendicular to a line I) representing the direction of the height of the shoe, and also to position it so that its axis inclined relatively to the direction of the length of the shoe, for example in approximately parallel relation to the ball line, as more particularly hereinafter explained by reference to Fig. 1.

Since the particular relation between the pad 26 and the shoe which is best for the I will be understood that at the innerv objects in view will depend somewhat upon the shape of the shoe, the invention further provides for varying that relation. The pad is supported in a pad holder 28 which has lower curved faces resting on similarly curved faces on the top of a block 30 so that the pad holder and the pad may be adjusted about an axis extending lengthwise of the shoeand located in the vicinity of the shoe, the pad holder 28 having at opposite sides of the block 30 depending flanges in one of which is a set screw 32engaging the block in a groove 33 therein for maintaining the pad holder in adjusted position. The block 30 is supported on plates 34 which are secured on the carrier 22, and the block is swiveled on a vertical stud 36 which projects upwardly from a rectangular'block 38 mounted in a horizontal guideway in the carrier 22. It will thus be seen that the'block 30 together with the holder 28 and the pad 26 are adjust able about the axis of'the stud 36, this axis extending heightwise of the shoe. As indicated in Fig. 1, the block 30 is preferably positioned in an angular relation to the edges of the underlying plates 34 corresponding to a position of the pad 26 in which the axis a of the pad is in approximately parallel relav I tion to the. ball line of the shoe. It will be evident also that by turning the block 30 the pad26 may be reversed end for end to position it for operating on both right and left shoes. Tohold the block 30 in adjusted position, as well as toprevent it from being lifted from the stud 36, there is provided a set screw 40 carried by the block and extending into a groove 42 in the stud. The pad 26 is also adjustable bodily lengthwise of the shoe by means of a spindle 44 having threaded engagement with the block 38 and mounted in a bearing in a plate 46 fast on the carrier 22, the spindle being held from lengthwise movement by collars 48 and 50 in engagement with the plate 46. The spindle 44 is provided with a hand wheel 52 for turn ing it. i

It will be evident that the pad illustrated has a thickness heightwise of the shoe equal to its extent lengthwise of the shoe, which renders its sufficiently yieldable in the pressure-applying operation to conform as re quired to the contour of the shoe while permitting it to bemade of a quality of rubber that is firm enough to apply the desired amount of pressure. While the pad could be made thick enough for the purpose in viewportion of the pad which operates on the shoe is somewhat greater than the length of the shank portion of the shoe, and it is contem plated that the pad will be so formed that the diameter of its shoeep-ressing port-ion will be at least as great as, and preferably somewhat greater than, the length of the shank portion of the largest shoe on which'the pad is to operate.

The pad holder 28 supports the pad by engagement with that side of it which is farthest from the shoe and. by friction prevents it from turning in the pressure-applying operation, the holder having a pad-engaging face complemental in shape to the curved periph cry of the pad. The curved face of the pad holder engages only the lower half of the pad and preferably terminates, as illustrated somewhat below the level of the axis of the pad, thus affording ample opportunity for such yield of the pad as to conform readily to the contour of the shoe in the pressureapplying operation. At the opposite ends of the pad the pad holder is provided with plane portions 54 which extend upwardly far enough substantially to cover the end faces *of the pad, this arrangement being regarded as preferable for proper control of the pad and to render it sufficiently firm to apply the required amountof pressure at and near the opposite side edges of the shoe bottom. 7 It is found that better'results' are obtained in conforming the sole to the general contour of the bottom of the last, without the presence of undesirable irregularities impressed thereon by portions of the shoe materials, if there is interposed between the rubber pad 26 and the shoe a cover of material which is considerably less yieldable than the pad, preferably a sheet of sole leather shown at 56. This'cover, however, is not secured to the shoe-pressing face of the pad, so that there 1s provision for relative creeping movement between the cover and portions of the V pad that are in contact therewith in the pres sure-applylng such relativemove'ment of different portions 7 operation. This facilitates of the rubber pad 'as to conform readily to the contour of the shoe and todistribute the pressure with approximate uniformity over the different portions of the shoe bottom. As illustrated, the cover is fastened only to the pad holder 28 by screws 58 applied only at those extremities of the cover which are oppositein the direction of the length of the shoe, its opposite side edges being left unsecured. The cover may thus be held substantially tight over the curved face of the pad when the pad is in its normal condition, since in the pressure-ap-plying operation the yield of the pad results in a slackness of the cover such as to facilitate relative creeping movement of the cover and the pad, as illustrated in Fig. 2. 7

It will thus be seen that the invention provides pressing means which, although not apvproximating very closely the shape of the pressing meansis adapted for use on right and left shoes and on shoes of various styles and sizes. Experience has, in fact, demonstrated that the same pad is adapted for use on all shoes within the entire range of adult-s sizes. In operation the pad accentuates its pressure initially in a location between the opposite side edges of the sole, whatever may be the style or size of the shoe, and then as it yields it wraps itself progressively around the laterally convex curvature of the shank portion of the shoe bottom while applying to all parts that are thus treated the necessary amount of shaping pressure. It will be evident that the pad herein shown in thus limited substantially to operation at the shank portion of the shoe, although on shoes of the smaller sizes, for example, it may overlap to a small extent portions located forwardly and rearwardly of the shank.

While the invention isherein'illustrated by referenceto its use on shoes'of that type having an outsole secured to. an insole by stitches passing through 'both the outsole and the insole, it will be understood that it is applicable to the manufacture to shoes of various kinds, including welt shoes and turn shoes.
